APPARATUS FOR MAKING GAS FROMOIL AND STEAM.

SPECIFICATION forming part of Letters Patent No. 438,071, dated October 7, 1890.

Application filed March 31, 1890.

To all whom it may concern;

Be it known that I, EDWIN R. ELLSWORTH, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Apparatus for Making Gas from Oil and Steam, of which the following is a specification.

My invention consists in an improved ap paratus for making gas from oil and steam, hereinafter fully described and claimed.

Figure 1 is a vertical'section. Figure 2 is a front elevation; Fig. 3, a rear elevation. Fig. 4 is a longitudinal section atomizer. Fig. 5 is an elevation of the gages ordinarily used in this class of work. Fig. 6 is a front elevation of the oil-valve, and Fig. 7 is a section on line 7 7, Fig. 1. A,

A represents a wall of masonry inclosing the apparatus, the rear upper part being usually made slanting, as shown at c, and wholly or partially movable. This part may be made of metal, tile, or other suitable material supported on uprights c.

0 represents a fire-place between the wall A and the bridge-wall B, having a fire-doorN and an ash-pit door N.

Y represents a coil of pipe for su perheatin g steam, the size of which is of course proportioned to the size of the apparatus, and it may be either a naked pipe or may be protected by being partly or wholly cast in a metal shield Y. This coil is located in the fire-place G, to be heated by the flame and products of combustion therefrom.

D represents another fire-place, usually smaller than C, on the other side of bridgewall B, and provided with a fire-door P and an ash-pit door P.

E representsa retort extending forward and upward across the apparatus, the rear end being directly over the fire-place D and the other end extending above fire-place O, as shown in Fig. 1. The top m of the retort is preferably made in a series of levels, each provided with a man-hole and plate 6, while the bottom is formed with steampassages K therein, and preferably in a series of curves, 1, though it may be straight.

as shown in Fig.

through the I Serial No. 346,091. (No man.)

0 represents aremovable platebolted to the front of retort E, to which the sprayer 0 5c is bolted by means of the projectingdisk 72, formed on said sprayer.

2' represents a perforated or slotted plate eX- tending vertically across retort E, thus forming a chamberl, into which the spray of oil and steam is thrown, and which passes through the perforated plate 2' into the retort.

R R R represent gas-pipes leading from the top of the retort E to the places where the gasis to be used.

X represents gages to indicate the pressure in the different oil and, steam pipes leading to the apparatus and the gas-pressure in the difierent retorts, for I usually put several sets of retorts in one apparatus, though of course this is optional.

X represents a gage showing the opening of the valve controlling an oil pipe or pipes.

M represents an oil-pipe leading from any convenient source of supply to the atomizer 0.

Z represents a steam-pump for forcing the oil through pipe M into the atomizer.

S represents a flue to lead the products of combustion from the furnaces to a stack. I prefer the arrangement shownwith two fireplaces or furnaces O and D, because this permits the superheating-coil Y to be heated to a high temperature without raising the lower partof the retort to a temperature so high as to produce gas-carbon therein, and the second furnace D permits the lower end of the retorts to be separately heated to'a temperature designed for working the apparatus; but of course the apparatus may be used with only a single furnace, if desired, in which case the bridge-wall B would be so proportioned as to permit the heat from furnace C to strike the retort ata somewhat lower point than shown in the drawings.

The ends of the coil Y (or of each coil) connect with a branch pipe Q, which is connected with a header K in front of each retort.

K represents pipes (one, two, or more to each retort) which lead from the header K to the atomizer O, forming steam-passages in the bottom ofthe retort, by which the temperature of the retort is equalized, the steam in passages K taking up heat if the fire becomes too hot, and giving out heat if the retort cools.

The atomizer O-consists of a hollow body of metal having an enlarged chamber R with tapering end R.

T represents a through the two stuffing-boxes u at, having a tapering end, and having a central bore 15, which opens through the wall of the plug, as shown in Fig. 4:. Steam enters the chamber B through pipe K, and oil enters the bore 15 of plug T through pipe M.

(represents a pivoted lever, by which plug T may be moved to vary the annular opening between it and chamber R W represents a frame, in which lever V is pivoted, and W represents ,a scale, by means of which and the pointer v on lever V the operator can determine the position of plug T. Of course there must be a loose connection between lever V and plug T, or else the frame W must swing. r

The operation of my invention is as follows:

Fires are built in the furnaces or' fire-places G and D, and steam from aboiler is admitted to coil Y. This steam becomes superheated and passes through the pipe K to the atomizer 0, where it meets a stream of oil coming under pressure through the pipe M and blows the oil in the form of a fine spray into the chamber I against the perforated or slotted plate i, by which it is broken up and more thoroughly mixed with the superheated steam and converted into gas. The gas then passes through the perforated or slotted plate i into the retort E, whence it is let through the pipes R to the places where it is used. By means of the slotted or perforated plate tthe oil is split or cracked up thoroughly and forms a better gas than where the oil is atomized directly into a large retort.

In the operation the fire in the furnace or fire-place D is regulated so as to heat the retort to such a temperature as will facilitate the conversion of plug sliding steam tight oil into gas without the danger of producing gas-carbon orlamp-black, and the retort is protected. from the intense heat of furnace or fire-place O by the intervenin g superheating-coil Y and by the steampassages K;

I have shown three retorts in a single apparatus, the object of this being to prevent stoppage of the apparatus by accident to one retort, and also to permit making different grades of gas at the same time for use in different furnaces. I prefer to separate the different retorts by brick walls rising between them, so that one retort can be cleaned while the next is running, or so that the difierent retorts may be run at different temperatures at the same time;

What I claim as my invention, and desire .to'secure by Letters Patent, is-

1. In anapparatus for making gas from oil 7 and steam, the combination of an inclined retort formed with a series of levels, each having a man-hole, of said retort, and an intermediate coil of steamsuperheating pipe, substantially as described.

2. In an apparatus for making gas from oil and steam, the combination of the inclined retort formed with a series of levels and having steam-passages in the bottom, a fire-place beneath each end of said retort, and an intermediate coil of steam-superheating pipe communicating with the steam-passages of the retort, substantially as described.

3. In an apparatus for making gas from oil and steam, the combination of an inclined retort E, formed with a series of levels andhaving a chamber I at one end and gas-exit pipes R at the other end, an atomizer O, communicating with the chamber I and provided with oil and steam inlet pipes, the fire-places G and D beneath the retort, and the intermediate coil of steam-superheating pipe Y, substantially as described.
